Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a streetlight head, and more particularly, to a streetlight head used in a streetlight that illuminates a road or the like using an LED as a light source.
Streetlights are mainly installed outdoors to illuminate the surroundings when the illuminance is low, such as night or cloudy days. There is a problem that the streetlight head is directly exposed to the outdoor environment because the streetlight is installed outdoors. For example, the influence of solar heat, sand, dust, and precipitation.
Recently, energy-efficient LEDs are widely used as light sources. In the case of LEDs, 20% of the supplied power is used for generating light and the remainder is dissipated into heat. If the heat is not discharged smoothly to the outside, There is a problem that is damaged.
For this purpose, it is generally made of aluminum die-casting or extruded structure to make a heater. However, aluminum die-casting or extruded structures are made of various alloys in order to improve workability. Due to the influence of this alloy, the heat conduction performance is reduced to about 70% compared with the heat conduction performance inherently possessed by aluminum, There is a problem of heavy weight.
In addition, a thermally conductive film material is conventionally used for bonding the substrate and the heat sink. However, since the heat conductive performance is relatively low and the fine pores are not penetrated, the heat radiation performance is poor.
In addition, the streetlight head is heated by the solar heat even during the day when the streetlight is not used, thereby damaging the light source inside the streetlight head.
It is an object of the present invention to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a lighting system that can smoothly discharge heat generated from a light source through natural convection while using a cover that blocks the light source of the streetlight head from being affected by an outdoor environment And prevents foreign substances or the like from entering the inside of the streetlight head.
Another object of the present invention is to maximize the heat transfer efficiency of the heat dissipating structure while reducing the weight of the radiator.
According to an aspect of the present invention for achieving the above object, the present invention provides a body including a front cover having a curved outer surface, a front plate coupled to the front cover and disposed toward the ground, A heat sink plate to which the substrate is attached and a heat radiating fin to which a plurality of heat sink plates are installed at a predetermined interval, Air is introduced into the main body through an inlet formed in a front plate corresponding to an edge of the window and passes through the vent hole and is discharged through an outlet formed in an upper region of the front cover The air is discharged to dissipate heat, and an outlet cover is provided at a predetermined height at the outlet of the outlet So as to prevent the foreign matter from entering directly from the outside to the outlet.
The discharge ports extend in the longitudinal direction of the front cover and are arranged in parallel, and the radiating fins are installed to extend in a direction orthogonal to the longitudinal direction of the discharge port.
And a protection fence protruding from both ends of the discharge port in a region where the discharge port is formed so as to block the transfer of foreign matter to the discharge port and to guide the air guided along the outer surface of the end cover to an area where the discharge port is formed Block transmission.
A drainage channel is formed between the discharge ports or between the discharge port and the guard fence in parallel with the discharge port.
The heat sink plate and the heat radiating fin are both made of an aluminum plate, and the bonding portion of the heat radiating fin is attached to the heat sink plate as active lead, and the heat radiating portions bent at the bonding portion are adjacent to each other at predetermined intervals.
The following effects can be obtained in the streetlight head according to the present invention.
In the present invention, in order to prevent the light source from being damaged by the outdoor environment, the end cover is used to shield the ventilation opening, and the air passing through the ventilation opening is configured to be natural convection. Therefore, since the discharge port is located at the upper end of the end cover, the rain cover, sand, etc. can enter the inside of the street lamp head through the discharge port. To prevent this, the outlet cover is provided on the outlet of the discharge port. It is prevented that precipitation or sand is prevented from entering, and the performance of the streetlight head is kept constant.
In the present invention, the heat radiating plate and the radiating fin are made of an aluminum plate without using a die casting or extrusion method, and they are joined by using active lead. Accordingly, the heat conduction between the components constituting the ventilation opening becomes more smooth, and the size and weight of the ventilation opening itself are minimized, thereby making it possible to miniaturize and lighten the entire streetlight head.
In the present invention, since the controller for driving the light source also has a door plate which is used to open and close the inside and the outside of the main body so as to allow the heat to be radiated to the outside well, There is also an effect of smooth discharge.
